**Note**: On distributed systems, root credentials are recommend to be defined by exporting the `MINIO_ROOT_USER` and  `MINIO_ROOT_PASSWORD` environment variables. If no value is set MinIO setup will assume `minioadmin/minioadmin` as default credentials. If a domain is required, it must be specified by defining and exporting the `MINIO_DOMAIN` environment variable.
